Let's say a motivated Lopez (like the one that thrashed Campas) moves up to 154 and faces the Ging. Who wins?
For now i'd favor Lopez. Canelo still isn't proven. Not that Lopez was a world beater but if anything he could bang and Alvarez is no defensive wizard.
If Lopez is motivated, I think he simply punches too hard and Canelo doesn't have the skills to really evade that.
